Question

Пж помогите 24 (1-3) и 25

Answer 1

24. 12 мин = $\frac{12}{60} = \frac{1}{5}$= 0.2 часа

5 мин = $\frac{5}{60} = \frac{1}{12}$часа

1 ч 30 мин =$1 + \frac{30}{60} = 1 + \frac{1}{2} = 1 \frac{1}{2} =$1.5 часа

25.

20/25 = 4/5 = 0.8

17/34 = 1/2 = 0.5

24/32 = 3/4 = 0.75

39/60 = 13/20 = 0.65

27/75 = 9/25 = 0.36

6/24 = 1/4 = 0.25
